Product Description

The Radium Engineering 20-1995-00 FCST-X Fuel Cell Surge Tank is engineered for high-performance fuel delivery systems where external or mechanical pumps are used. It features a drop-in, competition-grade design compatible with fuel cells that meet the 6"x10", 24-bolt standard, and offers excellent serviceability and flow capacity for aggressive builds.

With its high-flow architecture and robust construction, this surge tank is ideal for road-race, drag, track or boosted applications where keeping the fuel pumps fed under high-G or high-load conditions is imperative. While the kit does not include pumps, it provides the structural and plumbing platform for a serious fuel system upgrade - giving tuners, fabricators and racers the flexibility to select the pump setup that matches their specific performance goals.
